The damping structure 58 includes, for example, a one-way clutch 58A. The one-way clutch 58A is arranged between the rotational shaft 54X and the movable member 44. When the pulley assembly 56 rotates relative to the movable member 44 in the second rotational direction R2 about the rotational axis RA1, the rotational shaft 54X rotates integrally with the one-way clutch 58A. When the pulley assembly 56 rotates relative to the movable member 44 in the first rotational direction R1 about the rotational axis RA1, the rotational shaft 54X rotates relative to the one-way clutch 58A. The one-way clutch 58A includes, for example, a roller clutch.

The resistance-applying member 58B is arranged between the one-way clutch 58A and the movable member 44 to extend around an outer circumferential portion of the one-way clutch 58A. The resistance-applying member 58B tightens the outer circumferential portion of the one-way clutch 58A to friction-engage the one-way clutch 58A. When the pulley assembly 56 rotates in the second rotational direction R2, the rotational shaft 54X rotates integrally with the one-way clutch 58A. Thus, the resistance-applying member 58B applies rotational resistance force to the pulley assembly 56.

The description related to the above embodiments exemplifies, without any intention to limit, applicable forms of a component system for a human-powered vehicle, a derailleur for a human-powered vehicle, a rear derailleur for a human-powered vehicle, a charger for use with a component system for a human-powered vehicle, and a power source used for a human-powered vehicle component according to the present invention. The component system for a human-powered vehicle, the derailleur for a human-powered vehicle, the rear derailleur for a human-powered vehicle, the charger for use with a component system for a human-powered vehicle, and the power source used for a human-powered vehicle component according to the present invention can be applied to, for example, modified examples of the embodiments that are described below and combinations of at least two of the modified examples that do not contradict each other. In the following modified examples, same reference characters are given to those elements that are the same as the corresponding elements of the above embodiments. Such elements will not be described in detail.

As shown in FIG. 44 , the motor unit 66 can be arranged on the movable member 44. The motor unit 66 uses the electric motor to pivot the inner link member 62 about the second pivot axis PA2 and move the movable member 44 relative to the base member 42.

The power source receiving part 50 can be configured not to include the accommodation portion 68. In a case where the power source receiving part 50 is configured not to include the accommodation portion 68, for example, the structure of the cover member 48 can be changed as long as movement of the power source 90 disposed on the power source receiving part 50 is restricted.

As shown in FIG. 45 , the derailleur 40 can include the electric front derailleur 30. The base member 30A, the movable member 30B, and the linkage assembly 30C are respectively referred to as the base member 42, the movable member 44, and the linkage assembly 46, in a case where the derailleur 40 includes the electric front derailleur 30. The electric front derailleur 30 includes, for example, the base member 42, the movable member 44, and the linkage assembly 46. The linkage assembly 46 includes, for example, a power source receiving part 50.

As shown in FIG. 46 , the first power source 26 can be shaped in accordance with the shape of the first component 22. In FIG. 46 , the first power source 26 is disposed between the outer link member 60 and the inner link member 62 of the rear derailleur 54.

The linkage assembly 46 can be configured to include only the outer link member 60, and the at least one link pin 64 can be configured to include only the third link pin 64C and the fourth link pin 64D.

As shown in FIG. 48 , the first power source 26 can be arranged on the base member 32A of the electric rear derailleur 32. The second power source 28 can be arranged on the base member 30A of the electric front derailleur 30.

As shown in FIG. 49 , the first power source 26 can be arranged on the movable member 32B of the electric rear derailleur 32. The second power source 28 can be arranged on the movable member 30B of the electric front derailleur 30.

In the first to fifth, seventh to eleventh, and thirteenth embodiments, the first end 48X can be configured to be arranged closer to the damping structure 58 than the second end 48Y in a state where the cover member 48 is coupled to the at least one link member 52.

The relationship between the power source receiving part 50 and the reference line RL can be changed. For example, as viewed in a direction parallel to at least one of the third pivot axis PA3 and the fourth pivot axis PA4, a first region A1 and a second region A2 are defined. The first region A1 includes one part of a region divided by the reference line RL as viewed in a direction parallel to at least one of the third pivot axis PA3 and the fourth pivot axis PA4. The second region A2 includes the other part of the region divided by the reference line RL as viewed in a direction parallel to at least one of the third pivot axis PA3 and the fourth pivot axis PA4. The power source receiving part 50 can include a portion located in the second region A2 and a portion located in the first region A1 that is smaller than the portion located in the second region A2

The power source receiving part 50 can be formed separately from the outer link member 60. The power source receiving part 50 can be, for example, formed so as to be detachably attached to a recess of the outer link member 60.

The power source receiving part 50 can include a material differing from that of the outer link member 60. In a case where the outer link member 60 is formed of a metal member, the power source receiving part 50 can include a resin member.

As shown in FIG. 33 , in the first to ninth, twelfth, and thirteenth embodiments, the linkage assembly 46 can include at least one link pin 64 pivotally attaching the linkage assembly 46 to one of the movable member 44 and the base member 42. The electric port 72 can be arranged on the linkage assembly 46. In this modified example, the electric port 72 can be arranged on the linkage assembly 46, and the cable receiving opening axis CA can be inclined relative to the axis of the at least one link pin 64. The electric port 72 can be arranged on a side surface of the outer link member 60 so that the cable receiving opening axis CA is orthogonal to the axis of the at least one link pin 64. The electric port 72 can be arranged on an upward facing surface of the outer link member 60 so that the cable receiving opening axis CA is inclined relative to the axis of the at least one link pin 64. The electric port 72 can be arranged on a downward facing surface of the outer link member 60 so that the cable receiving opening axis CA is inclined relative to the axis of the at least one link pin 64.

As shown in FIGS. 50 and 51 , the damping structure 58 can include a fluid damper configured to apply fluid resistance to the pulley assembly 56 when the pulley assembly 56 rotates in the second rotational direction R2. The fluid is, for example, oil. The damping structure 58 is, for example, a hydraulic damper. In a case where the damping structure 58 is configured to apply fluid resistance, wear of the components is limited. This facilitates maintenance.

As shown in FIGS. 9 and 50 , the damping structure 58 includes a piston 92A, a piston support 92B, and the rotational shaft 54X, and a housing 92C. The piston 92A is supported by the piston support 92B. The housing 92C includes a fluid chamber 92D and a protrusion 92E. The rotational shaft 54X includes a hole 92F into which the piston 92A is inserted, a semicircular portion 92G in contact with the protrusion 92E of the housing 92C, and a hole 92H through which the fluid flows. The semicircular portion 92G has a smooth surface. The protrusion 92E smoothly moves on the circumference of the semicircular portion 92G.

The housing 92C is connected to the movable member 44. The rotational shaft 54X is connected to the pulley assembly 56. The rotational shaft 54X rotates integrally with the pulley assembly 56 about the rotational axis RA2.

In a case where the pulley assembly 56 rotates relative to the movable member 44 in the second rotational direction R2, the fluid in the fluid chamber 92D moves the piston 92A in a direction in which a flange of the piston 92A closes the hole 92H. The flange of the piston 92A restricts movement of the fluid through the hole 92H. When the hole 92H is closed by the flange of the piston 92A, the fluid moves through the gap between the semicircular portion 92G and the protrusion 92E. The fluid resistance hinders movement of the pulley assembly 56.

As shown in FIG. 51 , in a case where the pulley assembly 56 moves relative to the movable member 44 in the opposite direction of the pulley assembly 56, namely, the first rotational direction R1, the fluid in the fluid chamber 92D moves the piston 92A in a direction in which the flange of the piston 92A opens the hole 92H. This allows the fluid to move through the hole 92H, thereby reducing the fluid resistance to movement of the pulley assembly 56. As a result, the pulley assembly 56 readily moves in the first rotational direction R1.

The cover member 48 can be pivotally attached to and slidable on the outer link member 60. The cover member 48 can be configured to slide on the outer link member 60 and switch between a pivot allowed state and a pivot restricted state. For example, in the cover attachment state, the cover member 48 is configured to accommodate the pivot mechanism 40X in the recess of the outer link member 60 so that the pivot mechanism 40X does not function. The cover member 48 is configured to slide so that the pivot mechanism 40X projects out of the recess of the outer link member 60 when switching from the cover attachment state to the cover detachment state. The cover member 48 is configured to be rotatable about a pivot axis 40XA when the pivot mechanism 40X projects out of the recess of the outer link member 60.

As shown in FIG. 15 , the electric port 72 can be arranged on the base member 42. The electric port 72 of the base member 42 is, for example, used to perform at least one of charging of the power source 90, wired communication with a component 14 that differs from the derailleur 40, and wired communication with the external device 106. The electric port 72 of the base member 42 is, for example, used to perform at least charging of the power source 90. For example, in a case where a power source 90 that is arranged on the power source receiving part 50 is a rechargeable battery, the electric port 72 of the base member 42 is used to perform charging of the power source 90 arranged on the power source receiving part 50. The electric port 72 of the base member 42 can be configured to be supplied with electric power from a power source arranged on the component 14 differing from the derailleur 40. The electric port 72 on the base member 42 is, for example, configured to supply the motor unit 66 with electric power supplied from the power source arranged on the component 14 differing from the derailleur 40. The electric port 72 of the base member 42 can be configured to supply the motor unit 66 with electric power supplied from the power source arranged on the component 14 differing from the derailleur 40 in a case where the power source 90 is not arranged on the power source receiving part 50. The electric port 72 on the base member 42 can be configured to supply the motor unit 66 with electric power supplied from the power source arranged on the component 14 differing from the derailleur 40 in a case where the voltage of the power source 90 is less than or equal to a predetermined value.

As shown in FIG. 52 , the charger engagement portion 80C includes a charger rail 80F

The positional relationship between the charger rail 80F of the charger engagement portion 80C and the charger electric terminal 80B is set in the same manner as the positional relationship between the rail of the first housing engagement portion 26D of and the first power source electric terminal 26B of the first power source 26. Thus, as shown in FIG. 53 , the first housing 26A engages with the charger 80.

The positional relationship between the rail of the second housing engagement portion 28D and the second power source electric terminal 28B of the second power source 28 is set in the same manner as the positional relationship between the rail of the first housing engagement portion 26D of and the first power source electric terminal 26B of the first power source 26. Thus, as shown in FIG. 54 , the second housing 28A engages with the charger 80.

The positional relationship between the rail of the third housing engagement portion 34D and the third power source electric terminal 34B of the third power source 34 is set in the same manner as the positional relationship between the rail of the first housing engagement portion 26D of and the first power source electric terminal 26B of the first power source 26. Thus, as shown in FIG. 55 , the third housing 34A engages with the charger 80.

In the twelfth embodiment, the charger engagement portion 80C can be, for example, engaged with the first housing 26A by a mechanism differing from the first attachment engagement portion 22C and engaged with the second housing 28A by a mechanism differing the second attachment engagement portion 24C. The first attachment engagement portion 22C of the first component 22 can include, for example, the first rail 22D and the first attachment end part 22E. The second attachment engagement portion 24C of the second component 24 can include, for example, the second rail 24D and the second attachment end part 24E.

As shown in FIG. 56 , in the twelfth embodiment, the power source receiving part 50 can be arranged on a side portion of the base member 42. The power source 90 is attached to the side portion of the base member 42.
